Title: Production of transmission parts for driving power
Inventor: YOSHIDA KATSUYOSHI
IPC: B21K1/10
Filed: 1982-08-25
Abstract: PURPOSE:To obtain a product which has excellent strength, toughness and fatigue strength while the cost of production is kept low by using a steel pipe for a blank material, specifying the wall thickness ratio thereof and the outside diameter of a working part and joggling said part by drawing. CONSTITUTION:A steel pipe having 15-30% wall thickness ratio defined by the ratio t/D of a wall thickness (t) with respect to the outside diameter D of the pipe is partially drawn and is so joggled that the outside diameter D' of the worked part with respect to the outside diameter D of the non-worked part attains >=70%, that is, D'/D >=70%. An arbor 2 is inserted into the steel pipe 1 and the pipe is forged by using a die 3 in this case to accomplish such joggling by which the excess metal in the drawn part 11 is shifted to the stepped part 12. The thinning at the boundary between the non-worked part of a large diameter and the worked part reduced to a small diameter is thus prevented.

Title: Method for preventing overheat of print head drive element
Inventor: TSUCHIYA SATORU
IPC: B41J2/30
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of a print head drive element due to overheat by a constitution wherein a control part detects a junction temperature of the head drive element and executes a control of lowering the value of power flowing in the head drive element in the case when the temperature exceeds a prescribed one. SOLUTION: A central processing part (CPU) receives print data from host equipment and conducts a decoding processing thereof. The CPU reads out a junction temperature from a register R3 and executes a control of lowering a driving speed of a spacing motor so as to lower the temperature of a drive element 51 when the junction temperature exceeds a prescribed temperature (e.g. 120 deg.C). As the result, the speed of a printing operation of a wire-head print head 10 decreases. When the driving speed of the spacing motor decreases, the value of power flowing in the drive element 51 lowers and the temperature of the drive element 51 falls. In the case when the junction temperature is the prescribed one or below, on the other hand, the driving speed of the spacing motor is made a prescribed one. As the result, breakdown of the print head drive element can be prevented.

Title: Resistance value adjusting method of semiconductor device
Inventor: SOFUE MAMORU
IPC: H01L27/04
Filed: 1992-06-09
Abstract: PURPOSE:To adjust a resistance value without restriction on circuit design for a resistor after zap operation, by leading a zap current from the anode of a Zener diode to a zap equipment. CONSTITUTION:When a Zener diode ZD1 is zapped, a current source 4 is connected between pads 1a and 1b, the pad 1a is connected with ground GND, and a zap current IC is made to flow from the pad 1b to the ground GND. The cathode of the Zener diode ZD1 is kept at the potential of ground GND. The anode potential of the Zener diode ZD1 is remarkably decreased from the potential of the ground GND, and a sufficient zap current flows from the cathode of the Zener diode ZD1 to the anode. Thus the Zener diode ZD1 is zapped. Hence the state that a resistor R2 is connected in parallel with resistor R1 is obtained, and the value of the resistor R1 is finely adjusted, so that the restriction of cathode potential VA for circuit design can not be generated.
